Title: Measuring method and apparatus for standoff of semiconductor device and inspecting method for standoff of semiconductor device using the method and apparatus
Inventor: TANI YUKIO
IPC: G01N21/93
Filed: 1992-11-27
Abstract: PURPOSE:To automatically inspect the standoff of a surface-mounted IC. CONSTITUTION:A QFP.IC 1 is mounted on a jig 13 with mounting faces 4 of a group of leads 3 thereof pressed in touch with a reference face 14 of the jig 13. A measuring light 35 is cast between the reference face 14 and the lower face of a package 2 along the diagonal of the package by a measuring light casting device 34. The width of the measuring light passing through between the reference face 14 and the lower face of the package 2 is measured by a photodetecting device 36, so that the standoff as the minimum distance from the mounting face 4 of the lead to the lower face of the package 2 is measured. The measuring value of the photodetecting device 36 is compared with a preset value by a detecting device 38. Accordingly, the standoff of the QFP.IC 1 is automatically inspected. Since the mounting face of the QFP.IC 1 is butted to the reference face of the jig, the standoff can be inspected in the actually mounting state. The standoff is measured by the width of the measuring light, and therefore, processing of images can be omitted, thereby shortening the inspecting time and improving the inspecting accuracy.
